September will give way to October with the closing of a ‘summer of San Miguel’ which could be “the hottest” in the last 30 years, with maximum temperatures that will continue to rise progressively until the weekend, when the thermometers will be between 10 and 15 degrees above normalaccording to the State Meteorological Agency (AEMET), which warns that 38ºC will be reached in the Guadalquivir valley.
According to the spokesperson, Rubén del Campo, this is an episode of high temperatures that will be accompanied by absence of precipitation in most of Spain.
Specifically, it points out that the warmest days of this episode will be from Friday to Monday, when the maximums will be between 36ºC to 38ºC in the Guadalquivir Valley and will be between 32ºC to 34ºC in numerous areas of the interior of the peninsula as well as the Canary Islandswith fluctuations of 34ºC to 36ºC starting this weekend in the eastern islands.
Although the AEMET expects this heat episode to end in the middle of the first week of October, it warns that This ‘summer of San Miguel’ will be extensive and intense.
Del Campo explains that this hot episode is due to the atmospheric stability under high pressures, which favors clear skies, so the sun shines brightly and heats the surface quite a bit. Furthermore, he adds that light winds move the air mixture away, which is compressed and heated by the descents it makes from high to low levels of the troposphere within these high pressures.
